We provide a comprehensive overview of published research in the area, covering both usability and security aspects, as well as system evaluation. The paper first catalogues existing approaches, highlighting novel features of selected schemes and identifying key usability or security advantages. We then review usability requirements for knowledge-based authentication as they apply to graphical passwords, identify security threats that such systems should address, review methodological issues related to empirical evaluation, and identify areas for further research and improved methodology.<\/p>\n<p><a href=\"https:\/\/carleton.ca\/scs\/wp-content\/uploads\/sites\/260\/TR-09-09.pdf\">TR-09-09.pdf<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Carleton University Technical Report TR-09-09 November 24, 2009 Graphical Passwords: Learning from the First Generation Robert Biddle, Sonia Chiasson, P.C. van Oorschot Abstract Numerous graphical password schemes have recently been proposed as alternatives to traditional text password authentication.
